The weird implications of modern physics - reality itself may just be an illusion

For those working and studying modern science (especially in modern physics) will know just how very weird its implications have become. For instance, good old objects, things we can touch, smell and feel exist as a state of energy, while waves of probability spread throughout the universe. Existence itself may only be the vibrations on microscopic, trans-dimensional strings.
Attempts to solve problems in quantum physics often run into the problem of consciousness. Though most physicists try to sidestep the issue, it seems that there is a link between the conscious choice of experiment and the outcome of the experiment. In fact, reality itself may just be an illusion.
Schrödinger's cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935 to illustrate the weird implications of some interpretations (Copenhagen) of quantum mechanics when applied to everyday objects. The scenario presents a cat that may be simultaneously both alive and dead, a state known as a quantum superposition, as a result of being linked to a random subatomic event that may or may not occur. In this scenario a cat in a sealed box, wherein the cat's life or death becomes depended on the state of a radioactive atom, whether it had decayed and emitted radiation or not. Accordingly, the cat remains both alive and dead until the box is opened and observed by a conscious being.
In my book, The Illusion of Reality: A Public Servant’s Secret Essays, I discuss the interplay of light with elementary particles; the idea of emergence as the arrow of time and the role the conscience mind plays in integrating, and creating reality. Much of the book is based on theoretical and mathematical conjectures – however, recent news may change all that. A team of UC Berkeley researchers published a study recently detailing a miniature invisibility cloak that can conceal objects using the principles of quantum mechanical - remember Harry Potter’s cloak?
Under the lead of Xiang Zhang, director of materials sciences at the Lawrence Berkeley National Laboratory and professor in the campus’s department of mechanical engineering, the team created the first model of the cloak six years ago. The previous design, however, presented limitations because it was made of a bulkier material and needed to have a fixed shape.
Based on a completely different design principle, the more recent experiment has been capable of concealing a particle that is microscopic in size, researchers said it may be able to cloak larger objects as soon as five years from now. 
According to Zhang, there are many potential future applications of the technology. It could eliminate blind spots by making metal frames of cars transparent. Alternatively, the military may be able to use the technology to hide planes or tanks. Wrinkles and blemishes could be concealed with a design that would mold to the wearer’s features.

Verschränkung and Schrödinger's cat



Google's latest doodle marks the birthday of Erwin Schrödinger, the Nobel prize-winning quantum physicist whose eponymous equation lies at the heart of quantum mechanics.


He repeatedly criticised conventional interpretations of quantum mechanics by using the paradox of what would become known as Schrödinger's cat. This thought experiment was designed to illustrate what he saw as the problems surrounding application of the conventional, so-called "Copenhagen interpretation" of quantum mechanics to everyday objects.

Schrödinger proposed a scenario with a cat in a sealed box, wherein the cat's life or death depended on the state of a subatomic particle. According to Schrödinger, the Copenhagen interpretation implies that the cat remains both alive and dead (to the universe outside the box) until the box is opened and the function collapses.

For those who haven’t read Schrödinger or are not familiar with the man’s character - Schrödinger was a debonair, passionate, poetic philosopher and a romantic baronessck. He wrote books about the ancient Greeks, on philosophy and religion. He was influenced by Hinduism, flamboyant, cool, suave, sophisticated, dapper dresser and a big hit with the ladies.

It is said that Schrödinger’s promiscuity was legendary, having a string of girlfriends throughout his married life – some of them much younger than him. In 1925, the 38-year-old Schrödinger stayed at the Alpine resort of Arosa Switzerland for a secret liaison with an old girlfriend. It’s said that their passion proved to be the catalyst for Schrödinger’s creative genius.

Another physicist said of Schrödinger’s week of sexually inspired physics  - he had two tasks that week, satisfy a women and solve the riddle of the atom. Fortunately he was up to both. Schrödinger argued, crucially, that the electron was the wave of energy, vibrating so fast it looked like a cloud around the atom and went on to develop what is now known as the Schrödinger equation.  This describes the wave [completely] and hence the atom in terms of traditional physics.
